• Laminate is a UL Recognized Component that’s RoHS2 compliant and
Halogen free3 with high capacitance density that can be embedded
into PCBs and chip packages as either a power ground plane or a
discrete capacitor
• Consists of a very thin layer of ceramic-filled epoxy sandwiched between
two layers of copper foil
• Compatible with a large range of PCB material sets and with standard
PCB fabrication and assembly processes, including lead-free
• A variety of custom panel sizes and copper thicknesses available

Simplify design while amplifying performance
• Helps increase usable board area by allowing for the removal of many,
if not all, capacitors equal to or below 0.1 µF and their associated solder
joints and vias
• Helps improve power integrity by reducing power bus noise and
PCB impedance
• Helps reduce EMI by decreasing resonance that causes EMI
• Dissipates heat better than thin FR-4 due to high thermal conductivity
and low thermal impedance

1) All test data provided are typical values and not intended to be specification values.
2) “RoHS 2011/65/EU” means that the product or part does not contain any of the substances in excess of the maximum concentration values
(“MCVs”) in EU RoHS Directive 2011/65/EU. The MCVs are by weight in homogeneous materials. This information represents 3M’s knowledge
and belief, which may be based in whole or in part on information provided by third party suppliers to 3M.
In the event any product is proven not to conform with 3M’s Regulatory Information Appendix, then 3M’s entire liability and Buyer’s exclusive
remedy will be in accordance with the Warranty stated below.
3) Halogen Free is defined as both 1) no halogen compounds that are intentionally added to the product or used in the manufacturing process for
the product and 2) any impurities present are less than 900 ppm bromine, less than 900 ppm chlorine and/or less than 1500ppm total bromine
and chlorine. The latter are the levels set forth in certain industry standards for printed circuit boards, such as the International Electrotechnical
Commission (IEC) 61249-2-21 standard. This information represents 3M/s knowledge and belief which may be based in whole or in part on
information provided by 3rd party suppliers to 3M.
4) Epoxy default RTI temperature.
5) Dielectric thickness is provided for reference only since it correlates to the Capacitance density. Capacitance density is the product parameter
that is measured and controlled, and used to calculate the approx dielectric thickness reported on the Certificate of Conformance.
6) Copper thickness is not measured directly, but is determined by a “weight per area” factor to calculate thickness.
7) 100% electrical test is suggested for PCB applications larger than 2 square inches in area.
